VeriLinks: verifying links in an arbitrary linkset

VeriLinks is a light-weight platform for creating games to verify links in an arbitrary linkset. Agreement among players on the validity of a link is rewarded by coins or points. Depending on the specific game, those are then used to fight against enemy invadors in a tower defense style game or to battle using space ships. VeriLinks automatically balances the game such that the questions match the user's strength and the rewards match the difficulty of questions. VeriLinks features an admin console, which allows to create new games from a linkset by specifying the respective SPARQL endpoints, a template (for visual presentation) and the linkset itself.

Experiment 2012: Can we create better links by playing games?

In 2012, we officially released Veri Links and started a survey, which we distributed on Linked Data and Semantic Web mailing lists. We recorded in-game statistics and survey answers to obtain a clearer picture on the usefulness of games, in particular VeriLinks, for interlinking. The results and accompanying material for the experiments are available here:

Remark: Since people participated in the survey and played the game outside of the 3-day experiment phase, the raw data above are updated versions of those in the report.

Survey Winners (those who agreed that we can publish their names): Gianluca Demartini, Kingsley Idehen, Joe Montibello, Michael Röder, Jakub Kotowski, Thomas Efer, Virginia Knight, Ruby, Florent Jochaud
